2018-08-27x86: Don't mask out the GNU_PROPERTY_X86_UINT32_VALID bitH.J. Lu2-4/+6
Since only the GNU_PROPERTY_X86_UINT32_VALID bit may be set in data-only relocatable objects which don't contain any instructions, linker shouldn't mask out the GNU_PROPERTY_X86_UINT32_VALID bit when merging GNU_PROPERTY_X86_XXX bits. Otherwise, linker output doesn't contain GNU_PROPERTY_X86_XXX property with any data-only relocatable inputs. This patch keeps the GNU_PROPERTY_X86_UINT32_VALID bit and updates readelf to print "<None>" if GNU_PROPERTY_X86_XXX property only has the GNU_PROPERTY_X86_UINT32_VALID bit. bfd/ * elfxx-x86.c (_bfd_x86_elf_parse_gnu_properties): Don't mask out the GNU_PROPERTY_X86_UINT32_VALID bit. binutils/ * readelf.c (decode_x86_isa): Print <None> if bitmask only contains the GNU_PROPERTY_X86_UINT32_VALID bit.

2018-08-24x86: Update GNU_PROPERTY_X86_XXX macrosH.J. Lu2-60/+92
This patch updates GNU_PROPERTY_X86_XXX macros: 1. GNU_PROPERTY_X86_UINT32_AND_XXX: A 4-byte unsigned integer property. A bit is set if it is set in all relocatable inputs: #define GNU_PROPERTY_X86_UINT32_AND_LO 0xc0000002 #define GNU_PROPERTY_X86_UINT32_AND_HI 0xc0007fff 2. GNU_PROPERTY_X86_UINT32_OR_XXX: A 4-byte unsigned integer property. A bit is set if it is set in any relocatable inputs: #define GNU_PROPERTY_X86_UINT32_OR_LO 0xc0008000 #define GNU_PROPERTY_X86_UINT32_OR_HI 0xc000ffff 3. GNU_PROPERTY_X86_UINT32_OR_AND_XXX: A 4-byte unsigned integer property. A bit is set if it is set in any relocatable inputs and the property is present in all relocatable inputs: #define GNU_PROPERTY_X86_UINT32_OR_AND_LO 0xc0010000 #define GNU_PROPERTY_X86_UINT32_OR_AND_HI 0xc0017fff 4. GNU_PROPERTY_X86_FEATURE_2_NEEDED, GNU_PROPERTY_X86_FEATURE_2_USED and GNU_PROPERTY_X86_FEATURE_2_XXX bits. GNU_PROPERTY_X86_FEATURE_1_AND is unchanged. GNU_PROPERTY_X86_ISA_1_USED and GNU_PROPERTY_X86_ISA_1_NEEDED are updated to better support targeted processors since GNU_PROPERTY_X86_ISA_1_?86 aren't isn't very useful. A new set of GNU_PROPERTY_X86_ISA_1_XXX bits are defined.

2018-08-24x86: Add GNU_PROPERTY_X86_UINT32_VALIDH.J. Lu2-5/+19
The older linker treats .note.gnu.property section as a generic note and just concatenates all .note.gnu.property sections from the input to the output. On CET-enabled OS, the output of the older linker is marked as CET enabled, but in fact, it is not CET enabled and it crashes on CET-enabled machines.

2018-08-21Pack reloc_howto_structAlan Modra8-131/+138
This patch uses bitfields in reloc_howto_struct, reducing its size from 80 to 40 bytes on 64-bit hosts and from 52 to 32 bytes on 32-bit hosts (with a 32-bit bfd_vma). I've also added a new "negate" field rather than making the encoded "size" field do double duty as both a size and a flag. There was just one use of an encoded size of 8, which according to bfd_get_reloc_size meant 16 bytes, in vms-alpha.c ALPHA_R_LINKAGE. See git commit c3d8e071bf adding ALPHA_R_LINKAGE and git commit 8612a388f7 decoding size 8 in bfd_get_reloc_size. Since no other part of BFD handles 16 byte relocs, I've removed that encoding and special cased the ALPHA_R_LINKAGE size in vms-alpha.c. * reloc.c (reloc_howto_type): Typedef. (bfd_symbol): Delete forward declaration. (struct reloc_howto_struct): Add "negate" field.

commit 6404ab993797d1d6cd3d9e97cc281e3cb6226c12 Author: H.J. Lu <hjl.tools@gmail.com> Date: Wed Aug 8 21:00:04 2018 -0700 Convert .note.gnu.property section between ELF32 and ELF64 updated bfd_convert_section_size and bfd_convert_section_contents in bfd.c to call _bfd_elf_convert_gnu_property_size and _bfd_elf_convert_gnu_properties, which are defined in elf-properties.c. It led to bfd.c:2484: undefined reference to `_bfd_elf_convert_gnu_property_size' for non-ELF targets. Since elf-properties.c is a generic implementation and doesn't reference any ELF specific functions directly, this patch moves elf-properties.lo BFD32_LIBS. Tested for many ELF and non-ELF targets.

2018-08-10Always clear h->verinfo.verdef when overriding a dynamic definitionH.J. Lu2-7/+11
When linker defines a symbol to override a dynamic definition, it should always clear h->verinfo.verdef so that the symbol won't be associated with the version information from the dynamic object. This happened to the symbol "_edata" when creating an unversioned dynamic object linking against: 1. libKF5ConfigCore.so.5.49.0 2. libKF5CoreAddons.so.5.49.0 3. libKF5I18n.so.5.49.0 4. libKF5DBusAddons.so.5.49.0 5. libQt5Xml.so.5.11.1 6. libQt5DBus.so.5.11.1 7. libQt5Core.so.5.11.1 Among them libQt5Xml.so.5.11.1 299: 000000000003e000 0 NOTYPE GLOBAL DEFAULT 18 _edata@@Qt_5 libQt5DBus.so.5.11.1 597: 0000000000092018 0 NOTYPE GLOBAL DEFAULT 18 _edata@@Qt_5 libQt5Core.so.5.11.1 2292: 00000000004df640 0 NOTYPE GLOBAL DEFAULT 21 _edata@Qt_5 2293: 00000000004df640 0 NOTYPE GLOBAL DEFAULT 21 _edata@Qt_5 The problem is triggered by 2 duplicated entries of _edata@Qt_5 in libQt5Core.so.5.11.1 which was created by gold. Before this commit, ld created the dynamic object with "_edata" in its dynamic symbol table which was linker defined and associated with the version information from libQt5Core.so.5.11.1. The code in question was there when the binutils source was imported to sourceware.org. When such a dynamic object was used later, we got: /usr/bin/ld: bin/libKF5Service.so.5.49.0: _edata: invalid version 21 (max 0) /usr/bin/ld: bin/libKF5Service.so.5.49.0: error adding symbols: bad value Tested with many ELF targets.
